As How I Met Your Mother enters the homestretch of its final season, wrapping March 31 on CBS, speculation has been rampant that Ted's (Josh Radnor) titular bride-to-be has been dead the entire time his adult self has been narrating the series. (The most recent, overtly cryptic, episode only fueled the morbid argument.)

Cristin Milioti very politely disagrees. The actress, who stopped by The Hollywood Reporter offices the day before the final day filming the nine-season comedy, seemed genuinely put off by the suggestion the series would end on such a dark note.

"That's insane," says Milioti. "There are some crazy conspiracy theories, which really makes me love the fans more... That is so crazy."

Calling the finale "beautiful," she also notes that there weren't any alternate endings written or filmed in an attempt to maintain secrecy. "They've had this vision for nine years, and it's in great hands," she says of co-creators Carter Bays and Craig Thomas. "They know exactly what they want to do."

Could she be bluffing? Of course. She's had a few convincing performances of late. Milioti also chatted with THR about her turn as Leonardo DiCaprio's on-screen first wife in Martin Scorsese's The Wolf of Wall Street -- and how none of her co-workers noticed she was in it.

"I've had people from the show, that I work with, go to the movie and say, "Have you seen Wolf of Wall Street?,'" she says. "I never say anything."

CBS" final four episodes of How I Met Your Mother kick off Monday, Mar. 10, at 8 p.m.
